Hello everyone. I’ve a MacBook Air with an hard disk that I use as my memory for the Plex Server. Due to some issue I had to format everything, but now Plex doesn’t recognize the computer anymore and say it’s just “not available” (hope the sentence is right, my Plex is in Italian so I’m translating). Ho do I reconnect the computer to my Plex account?
Thank you very much
All the best

Did you reinstall your server from a backup (e.g. Time Machine) or did you install the server from scratch?
If you installed the server from scratch you’ll need to complete the installation by accessing the server through its local IP address – open [http://127.0.0.1:32400/web](http://127.0.0.1:32400/web) in a browser on that Mac or http://[MacBook Air IP address]:32400/web if you’re accessing it from a different machine. This should allow you to name the new server and link it to your Plex account.

If you restored the server from a backup you might need to clean up some parameters in the server configuration files:
1. stop the PMS
2. open `Terminal`
3. execute the following commands:
```shell
defaults read com.plexapp.plexmediaserver
defaults delete com.plexapp.plexmediaserver CertificateUUID
defaults delete com.plexapp.plexmediaserver MachineIdentifier
defaults delete com.plexapp.plexmediaserver ProcessedMachineIdentifier
defaults delete com.plexapp.plexmediaserver PlexOnlineToken
```
1. restart the server

At the end I had to reconnect all the folders and associates again the library, but in the end it worked. Thank you very much. 👍
